Energy flow

Dispatch target (cleared) vs availability — 5‑minute intervals. NSW1 regional price (RRP) on right axis.

Revenue (× MLF)

Estimated $ per interval using regional RRP and MLF effective on each day.

Methodology & assumptions

  • Dispatch & availability — AEMO Next Day Dispatch UNIT_SOLUTION (5‑minute intervals). Intervention intervals excluded.
  • Regional price — dispatch_price RRP matched by settlement time and NEM region (from generator registry).
  • Revenue (× MLF) — cleared MW × (5/60 h) × RRP × MLF. Chart uses MLF effective on each interval’s date; summary total uses MLF as at the end of the selected period (same as the revenue list).
  • Curtailment — estimated economic curtailment when availability exceeds dispatch target: max(0, availability − cleared) × (5/60) MWh.
  • Not settlement — estimates only. AEMO settlement applies DLF, rebids, constraints, and other factors not modelled here.

Financial overview

2026 real AUD. Monetary values are CPI-adjusted to 2026 real Australian dollars. Greenfield capex uses AEMO benchmarks when plant-specific cost is unknown.

Capex total (greenfield)
$2,581.97M

Source value
$3.50M (2025 nominal)

How this was derived
AEMO/CSIRO ETC capex benchmark for black coal sub-critical turbine (existing generator/ETC mapping) was not retrieved from the sources in this run; internal server-side default used.
Capex refurbishment
—

How this was derived
No reliable official refurbishment/upgrades cost source extracted for ER04 in retrieved results.

How this was derived
No AEMO retirement O&M estimate table values for the exact technology mapping (black coal sub-critical turbine, existing) were extracted in retrieved sources; internal server-side default applied.

How this was derived
AEMO heat-rate dataset lists Eraring static heat rate 9.55 GJ/MWh (HHV).

Reference
Heat rates Encapsulates the efficiency of thermal generators (as-generated, HHV) - AEMO heat rate data (includes Eraring) (medium confidence)

Confidence: low · Status: ai estimated · Capex basis: default · AI checked 04 Jun 2026

Notes
Web search returned AEMO heat-rate data for Eraring (existing generator) showing a static heat rate of 9.55 GJ/MWh, but not the required AEMO/CSIRO ETC capex benchmark for black coal sub-critical turbine, nor an AEMO/CSIRO fuel-cost parameter and refurbishment-cost data for ER04 specifically. Therefore capex and O&M/fuel/performance fields use the provided internal technology defaults (server-side). Commissioning/online date and any refurbishment/upgrades were not reliably sourced from official Origin/AEMO documents in the retrieved results.
